Food & Water Watch just released its 2010 Smart Seafood Guide to the safety and sustainability of more than 100 kinds of fish and shellfish. Now I still love the Monterey Bay Aquarium’s pocket guides and searchable Seafood Watch site (the only place where you can geek out with a trawling fact card, as far as I know), but the Smart Seafood Guide has a few unique features worth pointing out.

For starters, while some guides only address human health issues (like mercury) and environmental problems (like overfishing), Food & Water Watch also considers seafood’s socioeconomic impact. “For example, lobster is a a key part of the economy up in Maine,” says Marianne Cufone, director of Food & Water Watch’s fish program. “Knowing that fact is really important to some consumers.”

Another handy thing: It’s organized by texture and taste, so you can figure out the safest and most sustainable options in categories such as “mild” and “steak-like.” This makes it easy to figure out substitutes for recipes. 

Here’s Food & Water Watch’s “dirty dozen” list of seafood that failed to meet at least two of the group’s criteria. For more details, plus a list of alternatives for each verboten species, check out the guide. In no particular order:

1. King crab: Even though crab is abundant in some parts of the US, imports from Russia—which aren’t well regulated—are much cheaper and more common.

2. Caviar, especially from beluga and other wild-caught sturgeon: Overfishing and poaching of this coveted species is very common.

3. Atlantic bluefin tuna: Extreme overfishing, plus concerns about mercury and PCB contamination.

4. Orange roughy: May contain mercury and “is particularly vulnerable to overfishing due to its long lifespan and slow maturation.”

5. Atlantic flatfish (e.g. flounder, sole and halibut): Seriously overfished.

6. American eel: Concerns about mercury and PCBs.

7. Atlantic Cod: Overfished, and also has major bycatch problems.

8. Imported catfish: Much of it comes from Southeast Asia, “where use of chemicals and antibiotics is barely regulated.”

9. Chilean seabass: Concerns about mercury, plus illegal fishing in Chile damages marine life and seabirds.

10. Shark: May contain mercury, also overfished.

11. Atlantic and farmed salmon: Concerns about contamination with PCB, pesticides, and antibiotics. Also, waste and germs from salmon farms often leaches out of the cages and can harm the surrounding marine life.

12. Imported shrimp: About 90 percent of it comes from countries where the seafood industry (waste control, chemical use, and labor) isn’t well regulated.

TIME IS RUNNING OUT!

We have an ambitious $350,000 online fundraising goal this month and it's truly crunch time: About 15 percent of our yearly online giving usually comes in during the final week of the year, and in "No Cute Headlines or Manipulative BS," we explain why we simply can't afford to come up short right now.

The bottom line: Corporations and powerful people with deep pockets will never sustain the type of journalism Mother Jones exists to do. And advertising or profit-driven ownership groups will never make time-intensive, in-depth reporting viable.

That's why donations big and small make up 74 percent of our budget this year. There is no backup to keep us going, no alternate revenue source, no secret benefactor. If readers don’t donate, we won’t be here. It's that simple.

And if you can help us out with a donation right now, all online gifts will be matched thanks to an incredibly generous matching gift pledge.
